Answer:
Step-by-step explanation:
Given
initial Velocity(u)=44 ft/s
ball initial height =4 ft
as launch angle is not given so considering ball is hit vertically upward
where u =initial velocity
v=final velocity
a=acceleration
s=distance traveled
time taken to reach 30.06 ft
total distance to reach ground=4+30.06 ft=34.06 ft
t=1.45 s
Answer:
About 3 times faster
Step-by-step explanation:
Cheetah's speed = 110 km / hr
World 100m sprint record :
Speed of sprinter :
Distance / time
100 m / 9.58s
= 10.438413 m/s
Convert Cheetah's speed to m/s
110 km/hr = (110 * 1000)m / (60 * 60 s)
= 110000 m / 3600 s
= 30.55555 m/s
Number of times cheetah is faster than sprinter :
30.55555 m/s ÷ 10.438413 m/s
= 2.927 times
Answer:
C
Step-by-step explanation:
The central angle is 20% of 360°, that is
central angle = × 360° = 0.2 × 360° = 72° → C
The graph of the function is
- concave upward, when
- concave downward, when
Find
1.
2.
Now:
1. when the graph of the function is concave upward and this is for
2. when the graph of the function is concave downward and this is for
45/24 (simplified, it's 15/8)
The method is keep change flip.
keep the 9/4, change the division sign to multiplication sign, flip the 6/5 to a 5/6, then solve.
